The 32 Most Overlooked Reasons Why Marriages Fail

"One of the most overlooked reasons why marriages fail is how people define compromise. While compromise is considered to be the cornerstone of any relationship, most people assume that means that some of the time, each partner gets what they want. Actually, the true definition of compromise in the context of marriage is that neither party gets what they really want. Marriage is tough. You have to be constantly ready to give something up, even after it seems like you've already given up everything. Without accepting this definition of compromise, people move towards a break-up." —Ashwini Nadkarni, M.D., director of Digital Integrated Care in the department of psychiatry at Brigham and Women's Hospital and an instructor at Harvard Medical School

Think infidelity is the worst marriage-killer? The truth is even scarier than that — it really is the little things that will make or break your relationship.
